Notice that the stereo cassette arrangement allows you to use both sides of the cassette, by playing the tape in the other direction. The Porta02, however, uses the whole width of the tape. Notice also that
one pair of L and R tracks on the stereo cassette take up the same positions as tracks 1 and 2 on the Porta02. This can be important for your recording projects, as we will see later on. using the panpots, you can make the tracks appear to come from the left or the right speakers or anywhere in the middle. The technique of converting a multitrack recording to a stereo recording is called mixing down to a stereo master or mastering recorder. The Porta02 includes a mixdown section which allows you to mix to a stereo cassette or MD recorder.

1.1.2 Mixing down

Another advantage of multitrack recording is that when you come to make the nal version (on CD, cassette, etc.), you can adjust the level (volume) of each track, so that the piece sounds the way you want. As well as adjusting the track levels, you can also adjust the position of each track with regard to the left and right speakers. This is called panning, and the controls used to do this are called panpots. By
Some safety notes and precautions
Always use the PS-P2 power adaptor supplied with the Porta02. If you use any other adaptor, there is a risk of damage, or even re. Make sure that the input voltage marked on the PS-P2 adaptor matches the power supply you are using. If you are in any doubt, consult your TASCAM dealer. Turn off your Porta02 and remove the cassette when you are not using the Porta02. If you will not be using it for an extended period of time, unplug the PS-P2 adaptor. When connecting or disconnecting the Porta02 to or from any other equipment, make sure the power to the Porta02 and all other equipment is turned off. This will avoid possible damage to equipment. Do not keep your Porta02 in a very hot place. Remember that in sunny weather, the inside of a parked car heats up very quickly. Avoid leaving your Porta02 in such a place. Do not spill liquid onto your Porta02. Avoid eating, drinking and smoking near it (smoke particles are bad for
audio equipment). If any liquid or any objects such as paperclips, guitar picks, etc. fall inside the Porta02, do not try to operate it. Return it to a TASCAM service center for repair. If the case of the Porta02 becaomes dirty, clean it only with a damp (not wet) cloth, moistened with a little detergent. Do not use solvents or thinners, etc. to clean the Porta02, as these will damage the surface. There are no parts inside the Porta02 that you can repair by yourself. Do not open the Porta02 case or try to make any repairs. Return it to a TASCAM service center for repair.

1.2.1 Tape cassettes

Since the Porta02 uses the whole width of a cassette tape, you can only play and use one side of a cassette. You should try to use either side A or side B for all cassettes, to avoid confusion when changing tapes. Only use Type II (chrome or CrO2) cassettes with the Porta02. Find a reliable brand and stick with it. The time you spend creating your multitrack master is worth much more than the small difference in price between cheap and highquality cassettes. High quality cassettes will cause you fewer problems in the long run. To avoid having to wind and rewind a lot of tape, use the shortest possible cassettes for your projects. Remember that because you are only using one side of the cassette, the marked length of the tape will be halved (that is, a C60 tape will run for 30 minutes, a C40 for 20 minutes, etc.).
Never use C120 cassettes with the Porta02. The tape in these cassettes is thin, and may stretch and break.
Always store cassettes in a safe place (away from the magnetic elds produced by speakers, television sets, computer monitors, etc.). However, we suggest that you remove both tabs when you want to protect a Porta02 cassette. This will stop you putting in the cassette the wrong way round and recording over old material accidentally. be played back on a stereo cassette recorder. Also, note that if a cassette has been recorded with noise reduction, such as Dolby, etc., it will sound strange when played back on the Porta02. Any tapes (tracks 1 and 2) recorded on the Porta02 should be played back without noise reduction on a stereo recorder.
1.2.2 Record-protecting cassettes
The record-protect tab on a cassette stops you recording on that side when it is removed. The Porta02 also recognizes this protection, and will not allow you to record on the side of a cassette where this tab has been removed.
1.2.3 Playing back stereo cassettes
As mentioned earlier, the Porta02 can play back cassettes recorded on a stereo cassette recorder, using tracks 1 and 2. Also, if tracks 1 and 2 have been recorded on the Porta02, these cassettes can be played back on a stereo cassette recorder. However, if tracks 3 and 4 are used for recording on the Porta02, these cannot
1 An introduction to the Porta02 1.2.4 Cleaning the heads
You should clean the tape heads of the Porta02 regularly to keep it working properly. Dirt and tape oxide buildup on the heads will force the tape away from the tape head gaps that record and playback. Head cleaner will remove the dirt and restore the sound quality. In addition to affecting performance by coating the heads, and keeping the tape away from the recording and playback gaps, dirt and oxide in the tape path will also act in the same way as very ne sandpaper, which will wear down internal parts of the Porta02, and affect the recording in this way as well. All of these problems can be avoided if you buy a head cleaning kit such as the TEAC TZ-261 and keep it with your Porta02 for regular use. The kit consists of head cleaner, cleaner for the rubber parts of the Porta02, and cotton-tipped swabs. The cost of such a kit is less than the cost of a couple of high-quality cassettes and will pay for itself in better performance and longer life from your Porta02.

WARNING

Only use head and rubber cleaning uid and cleaning swabs designed for use with tape recorders. The use of any other cleaning materials may cause damage to the Porta02.
Clean the heads and metal parts of the tape path before every session with the Porta02 and also after every session.
Heads and tape guides Capstan Pinch wheel
1) Open the tape cassette cover. 2) Carefully clean the heads and metal parts as shown in the illustration using a swab dipped in the head cleaning uid. 3) Dry off the heads with a dry swab.
1.2.5 Cleaning the pinch roller
You should also clean the rubber pinch roller at regular intervals (at least once each day that you use the Porta02). 1) Open the tape cassette cover. 2) Press the PLAY key.
The pinch roller will engage with the capstan shaft and start turning.
3) Press a swab dipped in the rubber cleaning uid against the right side of the pinch roller.
If you press the right side of the roller, the swab will not get caught between the roller and capstan.
4) Dry the capstan with a dry swab and make sure that there is no material on the pinch roller or capstan before you insert a cassette.

2 Parts of the Porta02

What you need to make recordings
Some monitoring equipment (some kind of amplier and speaker system). Headphones, if you intend doing any work with microphones. These will avoid acoustic feedback (howlround) when recording. Additionally, headphones are sometimes useful when panning tracks on mixdown, as you can hear the precise position of each track. Of course, you will also need some kind of sound source to record (instrument or microphone, etc.).
Apart from the Porta02 itself, you will need: Some kind of stereo mastering recorder to produce the stereo recordings. This can be a cassette recorder such as the TASCAM 102Mk II or an MD recorder such as the TASCAM MD301. A recorder which does not have recording level controls is not suitable for use as a master recorder. You will also need RCA (pin or phono) cables to connect the Porta02 to other equipment.

Connecting the Porta02

You can listen to the Porta02 by selecting the ampliers input source to be from the terminals to which you connected the Porta02 (AUX or VIDEO, etc.). When you have mixed down and you want to listen to the mixed tape, you should select the mastering recorder as the ampliers input source.
1) Make sure all the equipment is turned off. 2) Connect the LINE OUT terminals of the Porta02 to the amplier, using a pair of terminals on the amplier such as AUX or VIDEO.
Do not use any terminals marked PHONO or intended for record decks. These are connected to a special circuit inside the amplier which makes them unsuitable for anything except record decks.

Left speaker

Right speaker
3) Connect your mastering recorder to a set of four TAPE terminals on the amplier (two for REC and two for PLAY). You may be using an integrated system in which the mastering recorder and amplier are built into one enclosure. In this case, you do not need to follow step 3.

Porta02 Mastering recorder
This section gives an explanation of the different parts of the Porta02, and what they do.

Parts of the Porta02

Parts of the Porta02 [1] POWER IN and switch [4] PHONES jack
Use this jack to connect the PS-P2 AC adaptor which comes with your Porta02. When connecting the power, make sure the power switch is off (slide it to the right, as you look from the back).
DO NOT use any adaptor with the Porta02 except the PS-P2 adaptor which comes with the Porta02.
This 1/4 jack allows you to connect a pair of stereo headphones to the Porta02.
Do not use headphones equipped with a mono jack. This will cause damage to the Porta02s headphone ampliers.

LINE OUT

Slide the switch to the left (looking from the back) to turn on the power to the Porta02.
Use these RCA (pin or phono) jacks to connect your Porta02 to the amplier or mastering recorder.

PHONES LEVEL

MIC/LINE 2
Use this 1/4 phone jack to connect the second channel audio source (instrument or microphone) to the Porta02.
The Porta02 is designed to record signals from microphones, CD players, tape decks and musical instruments. It is not designed to record signals which come from the speaker outputs of any amplier or equipment. If you try to plug such signals into the Porta02, you will almost certainly damage both the Porta02 and the other equipment.
This control adjusts the volume in headphones connected to the PHONES jack. Turn clockwise to increase the volume. There will be no output from the PHONES jack when the control is fully counter-clockwise. It has no effect on the level from the LINE OUT connectors.

MONO switch

When this switch is pressed down (in), it changes the stereo signal from the PHONES jack into a mono signal (the same signal will be output from both the left and right channels). Press it again to return it to the out stereo position. It does not affect the signal from the LINE OUT connectors.

MIC/LINE 1 (MONO)

TRIM (1 and 2)
Use this 1/4 phone jack to connect the rst channel audio source (instrument or microphone) to the Porta02. If you connect an audio source to this jack, but do not connect a source to the MIC/LINE 2 jack, the source at this MIC/ LINE 1 jack acts as a mono source, that is, it will be split between the rst and second channels as if you had plugged the same source into both jacks.
Different pieces of equipment output signals at different levels. The TRIM controls allow you to match the Porta02 to these levels. A piece of equipment such as a CD player or cassette deck will output signals at a high (LINE) level, so the trim control should be turned fully counterclockwise when such a device is being recorded. A microphone on the other hand, produces a lower signal level, and so the TRIM control should be turned fully

Channel faders (1 and 2)

These faders are used to adjust the level of the signals coming into the MIC/LINE
IN jacks. They should be used together with the TRIM controls (see 3.3, Setting the level) to adjust the levels of the signals routed to the tape tracks.

RECORD indicator

This red indicator lights when the RECORD and PLAY keys are pressed, and at least one of the REC FUNCTION switches is not in the SAFE position. Pressing RECORD and PLAY while both REC FUNCTION switches are set to SAFE has the same effect as pressing PLAY.
If the left record-protect tab of the cassette has been broken out, or if there is no cassette loaded, the RECORD key cannot be pressed. It is not possible to go directly from recording into playback mode. The PAUSE key only pauses playback and recording. It is not possible to pause the tape in fast forward and rewind modes. All keys lock down when pressed, except for the STOP key, and only work when locked down.

Transport controls

Cassette compartment cover
These work in the same way as the controls on most cassette recorders. However, there are a few points you should note: Pressing the RECORD key will also press down the PLAY key.
The hinged cassette compartment cover is opened by lifting the tab on the right side. There is no eject mechanism. You load and unload cassettes by hand, using a nger or ngers in the space to the right of the cassette.
3 Making your first recording
3 Making your rst recording
This section describes how to make a 4-track recording using the Porta02. For this, we will assume that you are making a recording of your voice on two tracks (1 and 2), using a microphone, and recording a part of a stereo CD or cassette on the other two tracks (3 and 4). Make sure you know what you are going to say. Start by making sure that you have all the equipment listed in 1.3, What you need to make recordings.

Setting up

1) Make sure all equipment is turned off. 2) Connect the LINE OUT jacks of the Porta02 to the AUX IN jacks of the amplier. 3) Connect the mastering recorder REC IN and PLAY OUT jacks to the appropriate jacks of the amplier. See 1.4, Connecting the Porta02 if you are not sure what you should be doing here. 4) With the INPUT 1 fader at the 0 position, plug the microphone into the MIC/LINE 1 jack. Do not plug anything into the MIC/LINE 2 jack.

If the microphone has a switch, make sure this switch is off.
5) Plug the stereo headphones into the PHONES jack of the Porta02. 6) Turn on the Porta02, the mastering recorder, and the amplier (in that order). 7) Set the ampliers input source to AUX (or the name of the jacks to which the Porta02 is connected).

Getting ready

1) Clean the heads and pinch roller (see 1.2.4, Cleaning the heads and 1.2.5, Cleaning the pinch roller). 2) Insert a Type II (chrome) cassette.
The tape should be towards the front of the Porta02, and the full spool should be on the left side. Put the non-tape part of the cassette in rst, and then push the tape (front) down into place
3) Play the tape for about 10 seconds and then stop the tape. 4) Press the counter reset button.

Setting the level

The aim of this section is to teach you to set the input level so that the average signals coming from the microphone will light the 0 meter indicator, and the loudest will light the +6 indicator. 1) Make sure all OUTPUT LEVEL controls are set to 0. Put on the headphones and set the PHONES LEVEL to the 0 position.
If you do not do turn down the speaker volume, you will probably get feedback (howlround) when you start using the microphone.
2) Set both TRIM controls to the LINE position.
Although you will probably end up with this control at the MIC position, or close to it, for now, set it to LINE.
3) Take the INPUT 2 fader to the 0 mark. Bring the INPUT 1 fader up to between the 7 and 8 marks.
This is called the nominal position, and is the position where the electronics controlled by the fader will not have to amplify the signal too much (causing noise) or have too much signal going into them (causing distortion).
4) Switch the microphone on if necessary. Speak into the microphone at the volume you will be recording.
It is important than when you perform these level checks that you speak, sing or play at the level at which you will actually be recording. Most people, when they rst start recording, tend to be a little louder than when they are simply checking the levels.
5) While talking into the microphone, turn the INPUT 1 TRIM control clockwise until the left 0 indicator is lit most of the time, and the +6 indicator is lit on the loudest parts.
If the 0 indicator hardly lights at all, you may be too far from the microphone, or you are speaking too softly. If the microphone uses batteries, you may need to replace them. You can also bring the fader up from the 7-8 position to increase the level, but you should do this only after the TRIM control has been turned fully clockwise.

6) Adjust the PHONES LEVEL until you are comfortable with what you hear in the headphones.

Recording the rst track

1) Set the REC FUNCTION switch of INPUT 1 to 1.
You are now ready to record on track 1. Make sure the REC FUNCTION switch of INPUT 2 is set to SAFE, so you dont record on it by accident.
2) Press the RECORD key (which will also press the PLAY key) and start recording the rst spoken track.
If the level as shown by the meters now seems a little high, you can back off on the fader a little.
3) When you have nished (try to keep speaking for at least a minute), press the STOP key. 4) Rewind the tape to the 000 mark. 5) Start playing the tape, and adjust the LEVEL and PAN controls of track 1 so that you can hear clearly what you have just recorded.
Note that meter 2 now shows the level of the tape replay on the right LINE OUT, rather than what is being input to the tape. NOTE
You may notice a difference between the sound you hear when you replay the tape and the sound you hear when you are recording. This is perfectly normal, and is due to the way that the Porta02 lets you hear previously-recorded material.
6) Rewind and replay the tape again, listening carefully to your recording. 7) Rewind and re-record the track as many times as you think necessary.
Of course, this is only a test, so it doesnt matter too much, but when youre making a real recording, its important to make the recording as good as possible.
8) When youre happy with the recording, set the REC FUNCTION switch of INPUT 1 to SAFE.
If you replay now, both meters will now show off-tape monitoring

Recording the next track

Since you plugged the microphone into MIC/LINE 1 / MONO, and didnt plug anything into MIC/LINE 2, the microphone signal is split as if it was plugged into both channels. 1) Take fader 1 to the 0 mark. 2) Set the level for input channel 2 in the same way as you set it for input channel 1 (see 3.3, Setting the level). 3) Set REC FUNCTION switch for INPUT 2 to 2.
You are now ready to record on track 2.
4) Rehearse your second spoken part by playing back the rst track (adjusting the level and pan if necessary) while speaking the words for the second track. 5) Rewind and record when you are ready.

When you are recording, the meter of INPUT 2 will show the input levels of input 2. Since the signal is now going to track 2, the meter for input 1 will not show anything.
6) Rewind and playback when you have recorded. Adjust the level and pan position of the two tracks with the LEVEL and PAN controls for tracks 1 and 2.
Remember that the fader adjusts the level of what goes onto tape, not the replay levels. When you are playing back, the meter of INPUT 1 will show the level of the signal from the left outputs, and the meter of INPUT 2 will show the input signal level as long as the REC FUNCTION switch is not SAFE.
7) Rewind and repeat the recording of track 2 until you are satised with it. SAFE input channel 2, and take both faders down to 0. Set the TRIM controls of both inputs to LINE.
Recording the stereo backing
Now that tracks 1 and 2 are lled with spoken words, well put some backing music behind them. Well assume that youre using a CD player here (of course, it may be an MD player or a cassette player).
This is a test recording and will not be used except as a test. However, if you are making recordings for public performance or distribution which include pre-recorded copyright material, you should be aware of the regulations concerning copyright in the area where you live. Unauthorized recording of copyright material may be illegal.
1) Make sure the volume on the amplier is turned all the way down (it should already be turned down). 2) Take off the headphones and unplug the microphone. 3) Connect the left and right LINE OUT of the CD player to MIC/ LINE inputs 1 and 2 of the Porta03. 4) Set the REC FUNCTION switches of INPUTs 1 and 2 to 3 and 4.
You are now ready to start recording on tracks 3 and 4.
5) Start playing the CD track you will be recording. Adjust the faders so that the +6 meter indicators light on the loudest parts of the CD. 6) Slowly turn up the amplier volume so that you are listening at a comfortable level. 7) Make the CD ready to play, and make sure that the Porta02 is rewound to the start of the recording. 8) Start recording, and start replaying the CD. 9) When you come to the end of the CD material, stop the CD and Porta02, and rewind the Porta02 tape to the beginning of the recording.

Mixdown

Make sure that your mastering recorder is connected to the monitoring system. 1) Set both REC FUNCTION switches to SAFE, and move both faders down to 0.
This will stop any extra unwanted noise from the inputs appearing in the nal mix.
2) Make sure the mastering recorder is ready to record, and put it into record pause mode. Do not start recording yet.
If you are using a tape for mastering, make sure that you are not recording over anything you want to keep. If you are using a new tape, make sure that you have taken the tape past the leader portion. Make the noise reduction, etc. settings on the mastering recorder, which will give you the best sound quality.
3) Play back the recording on the Porta02 and adjust the OUTPUT LEVEL and PAN controls on the Porta02.
The nominal position (the best position) for the LEVEL controls is about the 2 to 3 oclock position. This is the position you should regard as normal. It is usual to put the PAN controls for a stereo source such as a CD fully right and fully left. You can place the two voices anywhere in the stereo picture. Practice adjusting the levels of tracks 3 and 4 together to fade the backing music in and out.
4) While adjusting the levels on the Porta02, watch the recording levels on the mastering recorder. If they are too high, take down the recording level on the mastering recorder.
Remember that if you are recording on a digital recorder, such as an MD recorder, if the signal levels are too high, the result will be extremely unpleasant distortion. Analog recorders, such as cassette decks, will also distort if the levels are too high, but the distortion is much more pleasant (even so, you should try to avoid distortion in the mixdown).
5) When you are happy with the mix rehearsal, rewind to the start of the recording on the Porta02. 6) Start recording on the mastering machine, and start playback on the Porta02.
7) Mix the tracks, fading the backing music on tracks 3 and 4 to taste. 8) At the end, stop both machines. Rewind the mastering recorder. 9) Set the amplier input source to the mastering recorder, and replay your mix. 10) If you are not happy with the mix, you can do it again, either recording over the old mix, or adding the new mix after the old one. Congratulations! You have now completed your rst recording project with the Porta02. Rewind the Porta02 tape to the start, remove it, and clean the Porta02s heads.

4 Hints and advanced tips
This section gives a few hints and tips which may be useful to you when you make recordings using the Porta02.

Recording techniques

you, and there are several good books on the subject which can explain the theory of recording and some of the techniques.
Learning how to record is an art, not a science. One of the best teachers is experience. However, there are a few things mentioned here which may be useful to
4.1.1 Recording electric guitars
Much of the sound of an electric guitar (and also bass) is due to the effects, amplier and speakers, as well as the guitar and style of playing. If you plug the guitar straight into the Porta02, you will, of course, be able to record it, but the sound will probably not be what you are used to. Plugging effects units between the guitar and the Porta02 will certainly help to produce a fuller sound. The sound which will come closest to a live sound, though, will be provided by the amplier itself. You can adopt one of two approaches: either to put a microphone in front of the guitar speaker and record this (at MIC level), or to connect the output of the pre.amplier to the Porta02 and record at LINE level.
Do not connect the speaker output (or headphone output, if provided) of the amplier to the Porta02. This will almost certainly damage the Porta02, and may damage the amplier. Only use outputs which are marked LINE OUT, PRE OUT, DIRECT OUT and so on. Avoid using any outputs marked SPEAKER OUT, SP OUT, 4, 8, 16 or the like.
4.1.2 Recording with effects
Professional recordings often use effects like digital reverberation on vocals, etc. You can add some of these effects by plugging the microphone into an effects unit, and plugging the unit into the Porta02. Note that the effects unit must be able to accept microphone-level signals, and will output to the Porta02 at LINE levels. In addition, you will need to use the internal balance control in the unit to decide how much of the dry (un-effected) sound will be passed through to the Porta02 for recording. If you do not have access to a reverberation unit, you can try recording vocals in a very live room (without much furniture).
4 Hints and advanced tips 4.1.3 Metering

Tracing faults in a recording setup is often a mixture of logical deduction and patience. Very often, the problem is caused by something simple; a cable which hasnt been plugged in properly, or a faulty cable. If you discover a faulty cable, replace it with a new oneits not worth hanging onto bad cables!

If youre listening through headphones, is the Porta02s MONO switch pressed? If youre listening through speakers, is there a MONO switch on the amplier which has been pressed? When monitoring while recording, the sound will often be a little different to when it is played back. A large amount of distortion may be caused by recording at too high a level (shown by the meter +6 indicator being lit all or most of the time). Adjust the TRIM level and/or back off on the faders. If the meter +6 indicator is not constantly lit, you may want to reduce the headphone level; you may be driving the headphones too hard. Either the sound was recorded at too high a level, or the summed level of all four tracks is too high. Try reducing the level of all tracks so that the meter +6 indicator is not constantly lit on playback (set REC FUNCTION to SAFE). If one track only is distorted, it was recorded at too high a level. The heads are dirty. Clean them (see 1.2.4, Cleaning the heads) The capstan and pinch roller are dirty. Clean the capstan and pinch roller (see 1.2.5, Cleaning the pinch roller). Youre probably listening to tracks 1 and 2 forwards at the same time as 3 and 4 backwards. Turn down the OUTPUT LEVEL controls of tracks 3 and 4. If the sound is unnaturally bright, its quite likely that the tape was recorded on the other machine using noise reduction.
